Work History
This coal occurrence was first noted in 1887 by G.M. Dawson and first staked as Carol cl (Y27509) in May/68 by C. Sporer. Canex Placer acquired this occurrence as Coal Exploration Licence #61 in Oct/76, and as Licence #113 in Oct/79 and bulldozer trenched and drilled one hole (187 m) in 1977.
In Aug/94 Cash Resources Ltd acquired by application Coal Exploration Licences Y - 460 - 464 and in 1995 dug 3 trenches (TR - 12-14) near the occurrence.
Capsule Geology
Upper Paleocene or Lower Eocene coal of lignite A and B ranks is exposed in a trench. A 1.5 m thick seam underlain by grey claystone has an observed dip of 35°N. The sediments in the Watson Lake basin exhibit upward fining and thinning and are interpreted as point bar sequences produced by meandering streams.
Permafrost was encountered in all three trenches and no coal seams were encountered.
